HYBRID LINEAR ACCELERATOR WITH A BROAD RANGE OF REGULATED ELECTRON AND X-RAY BEAM PARAMETERS INCLUDES BOTH STANDING WAVE AND TRAVELING WAVE LINEAR SECTIONS FOR PROVIDING A MULTIPLE-ENERGY HIGH-EFFICIENCY ELECTRON BEAM OR X-RAY BEAM USEFUL FOR SECURITY INSPECTION, NON-DESTRUCTIVE TESTING, RADIATION THERAPY, AND OTHER APPLICATIONS
A Hybrid (SW+TW) Linear Acellerator is disclosed having high beam efficiency and broad energy regulation that is useful for security inspection, non-destructive testing, radiotherapy, and electron beam irradiation of objects. The Hybrid Linear Accelerator (LINAC) provides superior energy regulation, and includes a reversed RF power distribution which substantially improves RF power utilization, thereby eliminating need for an output RF load, and ensuring broad electron beam energy regulation operating in a broad range of input RF power, thereby efficiently running at a variety of input electron beam current intensities at high efficiency. The Hybrid LINAC may be equipped with a fast and/or slow phase shifter and/or a power regulator having a phase shifter and a current regulator, while operating much more efficiently than known LINACS. The Hybrid LINAC permits efficient operation without an external magnetic field, thereby avoiding use of a power-consuming solenoid, consequently reducing cost of production, o
